  • Patent number: 11921097
    Abstract: A method for dynamic measurement of individual tree carbon sink, including: 1. Individual tree survey and equipment arrangement; 2. Automatic data collection of individual tree; 3. Computation of individual tree carbon sink: computing height, volume, biomass, and carbon storage of an individual tree by using the data collected in step 2; 4. Detecting state changes of an individual tree, and performing step 6 if it changes, otherwise performing step 5; 5. Continuous monitoring of individual tree carbon sink: continuously receiving the data collected in step 2 at set monitoring frequency and performing step 3, while storing the data; 6. Verification on the monitoring state of the individual tree.
